tizen: Set the smack label of /dev/mapper and /dev/mapper/control as '*'
Normally, /dev/mapper and /dev/mapper/control are created by the in-kernel dm driver
and the smack label is set by Systemd as '*'.
When the dm driver is loaded as a module (dm-mod.ko), however,
/dev/mapper's label cannot be initialized by Systemd.
drwxr-xr-x root root * /dev/mapper
crw------- root root * /dev/mapper/control
